IMPROVEMENT IN SNOW-FLOWS.

Specification forming part of Letters Patent No. 143,095, datedSeptember 23, 1873; application filed May 31, 1873.

To all whom it may concern.-

Be it known that I, WILLIAM J. RoBERTs, of Cold Spring, in the county ofPutnam and State of New York, have invented a new and useful Improvementin Snow-Flows, of which the following is a specification:

The invention relates to the revolving cones used upon snow-plows; andconsists in the improvement hereinafter described and pointed out in theclaim.

In the accompanying drawing, Figure l is a side view of the snow-plow,shown as connected with a locomotive. Fig. 2 is a top view of the wheeldetached.

Similar'lettersof reference indicate corresponding parts.

A represents the locomotive. B is the shaft or axle of one of thedriving-wheels. C is the revolving bucket-wheel, which is arranged infront of the locomotive on a vertical shaft,

and is revolved by means of a belt, band, or

chain, from a pulley on the axle of the locomotive to the pulley E onthe vertical wheelshaft, the band or chain being seen in dotted lines. Fis the frame of the snow-plow. The plow or wheel 0 is the frustum of asolid cone, revolving around and with the vertical shaft. The sides ofthe cone are at an angle with the base of about thirty-five degrees,more or less. H represents the buckets or Wings, the outer edges ofwhich are parallel with the side of the cone, the ends being cut on theplane of the base and upper surface of the cone. I is the cap-plate ofthe plow. On the top of the pulley E of the vertical shaft is a clutch.The pulley E has the half of a clutch-coupling at tached to its upperside, and on the shaft above is the other half of the coupling, whichworks on a feather on the driving-shaft. This loose upper clutchrevolves with the shaft, and is dropped down by means of a screw orotherwise, and engages with the pulley-clutch when it is desired to runthe snow-plow. This arrangement is seen in dotted lines in the drawing.

. As the locomotive moves forward the wheel clears away the snow fromthe track and throws it to one side. It may be arranged by crossing thebelt or chain to reverse the motion and throw the snow either to theright or left.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The revolving cone-wheel 0, having the wings H,applied in front of a locomotive, as and for the purpose set forth.
